The reports of the great criminal trials before the _comitia_ reveal the inherent weakness of a system of popular jurisdiction in criminal matters. Personal and political considerations foreign to the merits of the case were allowed to take the place of competent evidence; and issues of right and expediency were too frequently mixed up. The accused, at times, trusted not so much in the righteousness of his cause as in the feelings of compassion and prejudice that moved the people as popular judges. And to excite these feelings the most ludicrous and undignified steps were sometimes taken. The defendant nearly always appeared at the trial in mourning garb, frequently let his hair and beard grow long, and often exhibited the scars and wounds received in battle whilst fighting for his country. He sometimes offered prayers to the immortal gods and wept bitterly; at other times he caused his children and other relatives to appear at the trial, wailing, and tearing their clothes. Not content with presenting all the pathetic features of his own life, he left nothing undone to expose his opponents to hatred and contempt. It thus happened that many of the great criminal causes of Rome were mere farcical proceedings. A few instances may be cited. Horatius, though tried in the time of the third Roman king, was pardoned by the people for the murder of his sister because of his heroic deed in single combat with the three Curiatii, and because his father had lost three children in the service of the state. In the year 98, Manlius Aquillius, the pacificator of Sicily, was tried for embezzlement. Marcus Antonius, his advocate, ended his argument for the defense by tearing the tunic of Aquillius to show the breast of the veteran warrior covered with scars. The people were moved to tears and Aquillius was acquitted, although the evidence was very clear against him.
